It's hard to keep up with all the changes in K-12 education standards. We hear about the evolution of Common Core and Next Generation Science standards as well as curriculum offered through the Environmental Education Initiative. All programs stress the need for hands-on, outside learning, but how can UC Agriculture and Natural Resources activities help to raise the next generation of scientists and land managers at its Research and Extension Centers?
As a newly employed community educator at the

Conventional breeding of cattle over decades has resulted in significant positive impacts for dairies and the environment. With genomics, the future looks still brighter.
For the most part, dairy operators select cattle for breeding that have the highest genetic potential for milk production, health, structural soundness and fertility. The introduction in the 1940s of artificial insemination from bulls that were proven to father productive daughters resulted in dramatic changes to the industry, according to geneticist Alison Van Eenennaam, UC Cooperative Extension specialist with UC Agriculture and Natural Resources.
“In the U.S., we used...

Cattle ranchers in California, Nevada and Oregon are one step closer to having a vaccine available to treat a tick-borne bacterial disease – commonly known as foothill abortion – which kills cow fetuses.
The USDA approved the expansion of ongoing field trials in November for an experimental vaccine, developed by UC Davis veterinary researchers, after it was shown to be effective in preventing foothill abortion in more than 2,000 cattle.
Foothill abortion – endemic in California's coastal range and the foothill regions of California, Southern Oregon and Northern Nevada – is a bacterial disease in cattle also known as epizootic bovine abortion. It is a major cause of...
To protect forests and homes from wildfire, vegetation is often removed to reduce fuel for a fire. But how do those forest management treatments affect fire risk, wildlife, forest health and water?
Since 2006, a team of University of California Agriculture and Natural Resources scientists has been studying the effects of vegetation management in the Sierra Nevada forest on fire behavior, forest health, water quality and quantity, the Pacific fisher (a small mammal in the weasel family) and the California spotted owl. The researchers are writing up their final reports and seeking public feedback on their recommendations and next steps in the process.

When a hiker on a San Francisco Bay Area parkland unknowingly walked between a cow and her calf, the mother came over, knocked the hiker down and stepped on him. In another incident, a woman walking her dogs off leash was chased by cows. She slipped and sprained an ankle.
Such incidents, though rare, prompted UC Agriculture and Natural Resources (UC ANR) experts to write guidelines for people who hike, cycle or ride horses in natural areas where grazing cattle are used to manage the land. The...
